Textbook Problem

(a) Sketch the plane curve with the given vector equation.

(b) Find r'(t).

(c) Sketch the position vector r(t) and the tangent vector r'(t) for the given value of t.

6. r(t) = et i + 2t j, t = 0

(a)

To determine

To sketch: The plane curve with the vector equation r(t)=eti+2tj,t=0.

Explanation

Write the x-component of the vector r(t)=eti+2tj,t=0.

x=et

Take natural log on both sides of the expression.

ln(x)=ln(et)

Rearrange the expression ln(x)=ln(e2t) as follows.

ln(x)=tt=ln(x)

Write the y-component of the vector r(t)=eti+2tj,t=0.

y=2t (1)

Substitute ln(x) for t in equation (1),

y=2ln(x)

The required curve is a graph of y=2ln(x).

Find the vector r(t) at t=0

(b)

To determine

To find: The vector r(t) from the vector function r(t)=eti+2tj,t=0.

(c)

To determine

To sketch: The position vector r(t) and the tangent vector r(t) at t=0.
